NHS 'black hole' - the size of the funding gap to 2020

The future shortfall in funding faced by the NHS in England will depend on the level of cost savings the NHS achieves.

If it makes no savings and funding rises only with inflation, the estimated gap will be at £30 billion by 2020/21. If it makes savings of 2-3% that gap falls to £8 billion.

That's an optimistic target. Savings have been estimated at 1.5% a year from 2004/05 to 2011/12. And analysis suggests the performance of hospitals has fallen back in the following two years.

NHS leaders say there must be upfront investment in transforming the service in order to meet the target, while others have said that although transformation will lower costs it won't do it by 2020.

Size of the shortfall

In the coming years the NHS in England is going to need to provide more services to more people in coming years due to, among other things, an increasing population and an increasing number of elderly patients.

If it's going to provide the same sorts of services at the same quality to more patients than it currently does, it will either need more money on top of inflation or to find ways to make the money it does have go further. Or both.

So to estimate the size of the shortfall—effectively the amount of money the NHS will need from government—we need an estimate of how quickly it improves its efficiency.

Four possible futures were set out last year by a range of leading organisations in the English NHS. The Five Year Forward View considers the size of the shortfall based on different levels of efficiency savings.

In the least optimistic scenario, the NHS makes no efficiency savings. Even if its funding keeps pace with inflation, there'd be a £30 billion per year shortfall by 2020/21.

Even the most optimistic predictions on efficiency savings mean £8 billion a year above inflation would have to be found to close the gap. That would require efficiency savings of about 2-3% per year.

Looking further ahead from now to 2030/31, separate research by the Health Foundation has put the spending required at £65 billion a year if efficiency savings are 1.5% a year or £48 billion if savings are at 2.2%.

Efficiency savings—the challenge

Efficiency savings allow the NHS to treat more patients or treat them at a better quality, or both, for the same amount of money (at least once the effects of inflation have been stripped out).

Between 2004/05 and 2011/12 the NHS is estimated to have made efficiency savings of about 1.5% per year. That means for every £100 it spent in a given year it only spent £98.50 on the equivalent services in the next one (again, leaving out inflation). But analysis by the Health Foundation suggests efficiency savings may have slowed down in the following two years, 2012/13 and 2013/14.

So efficiency savings of 2-3% in the next parliament would represent a big jump.

There are also concerns that the NHS has exhausted the easier and more "obvious" routes towards making savings, such as restricting pay rises for staff.

The King's Fund think tank has said closing the gap to £8 billion would be "very challenging". Others have suggested that measures to transform the NHS are likely to improve efficiency, but after 2020 rather than before.

The Five Year Forward View says that if efficiency savings are to be made in time to close the gap by 2020/21 then money needs to be put into transforming the way parts of the NHS operate. The NHS would need "infrastructure and operating investment to rapidly move to the new care models and ways of working described in this Forward View".

So what could that mean in practice?

NHS transformation—the "vanguard" sites

NHS England says it is working with a small number of areas "with the aim of developing prototypes that work, before promoting the most promising models for adoption by the wider NHS."

29 sites in England have been chosen to be at the vanguard of transformation. The types of organisation that are involved vary across different sites.

At nine of them, primary and acute care will be integrated. In the first instance that could mean, for example, hospitals opening their own GP surgeries. In some cases the hope is that patients could have all their health needs from GP to hospital treatment arranged and delivered by this one organisation.

At a further fourteen sites, the focus will be on expanding GP groups to include nurses and hospital specialists so that they can provide some outpatient care outside of hospital settings.

The final six sites chosen will focus on improving healthcare in care homes by working with care home providers and local social service departments.
